Where do you think I should start to find out if something is holding it open?
Loosen up both rockers and check leakdown.

Well I'll tell you but I don't know what to make of it because it's evidently past
the point where I know what I speak of, I was thinking collapsed valve but after
doing a search it appears it is instead the lifters that collapse.

Oh crap, wait!

The lifter is that spring thing, the piece that the push rod pushes up against would be the rocker arm?

See man

Let me go see if I can find a diagram of this mess.

Yeah all right, one more time...

That thing the push rod keeps popping out from under would be the rocker (or rocker arm)
and on the other end that spring thing is the lifter, then below that would be the valve.

I think I got it right this time.
Best I could find in terms of a diagram is this automotive VTEC which, well:

This push rod pushes UP on a lifter, the thing that it keeps popping out from under is called a lifter.
On the other end of that lifter is your valve.

Beyond that I have to leave it to the experts.
At the bottom end of the pushrod is the LIFTER or TAPPET which in Kaw engines is usually solid as opposed to Kohler which uses hydraulic LIFTERS.
The LIFTER acts on the PUSHROD which in turn acts on the ROCKER ARM which acts on the VALVE to open it.
So, your pushrod keeps popping out from under the ROCKER ARM.

Truly, you should leave it to the experts!!!! LOL

This is definitely not a push rod motor. A push rod motor has a lifter on camshaft that pushes up to open the valve and the down to close the valve.

This engine defintely has pushrods. It lso has tappets (lifters). Look at the picture, the part that popped out is a pushrod. People, if you do not know what you are talking about, please do not post. It is confusing the guy even more.
My advice to Just some Dude is take it in to a reputable service shop. It appears that you are in over your head on this one.
